May 10, 1932. s. E. MELKMAN HAIR WAVING DEVICE Filed Feb. 26, 1930[nvenimr Patented May 10, 1932 UNITED STATES PATENT @FFICE HAIR WAVINGDEVICE Application filed February 26, 1930, Serial No. 431,509, and inCanada February 27, 1929.

The present invention relates to improvements in hair waving devicesespecially of the type employed for forming lasting Marcel waves.

5 An important object of the invention is the provision of a hair wavingdevice which will form the curls and waves quickly and in a lastingmanner.

A further object of the invention is the provision of a hair wavingdevice having a mandrel disposed for partial circumferential movement toimpart an ironing or calendering effect to the hair.

Another object of the invention is the provision of a hair waving devicehaving a mandrel mounted for oscillating movement.

Still another object of the invention is the provision of a hair wavingdevice embodying amandrel mounted for partial circumferentialoscillating movement and means for operating the mandrel to efiectivelypress the hair.

Other objects and advantages of the invention will become apparent asthe description progresses.

In the accompanying drawings forming a part of this specification and inwhich like reference characters are employed to designate correspondingparts throughout the 39 same Figure 1 is a perspective view of theassembled waving device;

Figure 2 is a longitudinal sectional view through the same; Figure 3 isa transverse section taken on the line 33 of Figure 2, in one position;

Figure 4 is a similar view showing the mechanism in opposed position,and v Figure 5 is an enlarged transverse section taken on the line 5-5of Figure 2.

Referring to the drawings, wherein for the purpose of illustration isshown a preferred embodiment of the invention the numeral 10 generallydesignates a transversely elongated casing formed in the upper portionof its front wall with an opening and in the lower portion of its rearwall with a rearwardly directed annular flange 11. The up- W per portionof the casing 10 supports a man drel 12 embodying an exterior metallicshell portion of the mandrel 12.

13 of elongated tubular form carrying at its interior an electricheating element 14. One end of the mandrel is disposed in theupperortion of the casing 10 and is journalled for partial circumferentialmovement there 5 A rearwardly extending casing extension 15 is attachedto the flange 11 and is formed at its rearward extremity with acomparatively fiat, transversely elongated gear housing 60 16. Anextension section 17 extends rearwardly from the lower portion of thehousing 16 and forms a conduit for a poweroperated drive shaft 18.

Journalled within the casing extension 15, 65 so that one end projectswithin the lower portion of the casing 10 while the opposed or 70 on andoperates within the lower portion of .the casing 10. The gear 20 isdisposed immediately below and is in mesh with a complementary spur gear21 fixed on the inner The rear end of the transmission shaft 19 carriesa crank 22 rigidly fixed on the shaft and provided with a depending arm23 in the outer extremity of which is mounted a rear- .wardly extendingpin 24. 0

On the forward extremity of the drive shaft 18 is fixed a crankactuating cam 25 embodying a flat annular plate rigidly secured to thedrive shaft and formed at its forward the cam groove 26 so that thecrank 22 will be oscillated upon rotary operation of the cam 25.

The heating element 14 of the mandrel is on electrically connected witha source of electrical supply through the medium of conduc- 30 is bentto assume an arcuate form in cross 10o section designed to conform tothe exterior contour of the mandrel shell and to clamp the hair on themandrel over practically the entire length thereof. The opposed end ofthe clamping member is formed with a rearwardly extending operatinghandle 31 disposed for convenient adjustment by the operator.

In use,-the strands of hairare initially arranged flat upon the mandrel12 andare firmly clamped thereon by adjustment of the clamping jaw '30.The electric heating element is energized and the drivingconnectionproperly efi'ected so that the mandrel will be actuated in a partialrotary movement or rather circumferentially oscillated. This movement ofthe mandrel simultaneously with the heating, will producean ironing orcalendaring efl'ect to the hair sothat the Marcel waves will be rapidlyformed 'in a lasting manner.

It is to be understood that the form of my invention herein shown anddescribed is to be=taken as a preferred example of the same,andthat'various changes-as to the shape, size, andarrangement of partsmay-be resorted to without de'partingfrom the spirit of the invention'or the scope of the subjoined claims.

-Havingdescribed my invention, I declare that what I claim and desiretosecure by Letters Patent is 1. -A hair waving device comprising acasing, a hollow'm'andrel having'one end jour- 'nalled in the casing, aclamping member operable to clamp the hair on the mandrel, means withinthema'ndrel for heating it, and mechanism for circumferentiallyoscillating the said mandrel independently of the clamping member. a

2. In a hair waving device, a casing, a mandrel having one endprojecting in the casing and journalled therein,-a clamping'memlow'mandrel having one end journalled in the casing, a clampingmember operable to clamp the hair on the -mandrel, electric heatingmeans disposediin the mandrel, a rotar drive shaft, and actuating meansoperative y connected with the drive shaft and with the mandreladapted-to impart a circumferential oscillating movement to the mandrelupon rotary operation of the drive shaft.

4. Ina hair waving device, a casing, a hollow mandrel having one endjournalled in the casing, a clamping member pivotally connected with thecasing operable to clamp the hair on themandrel, electric heating meanswithin .the mandrel, a transmission shaft 7 journaalled in the casing,and intergeared with
